To ali whom it 'may concern:

Be 1t known that I, HENRY I. LEA, a citizen of the United States, and a resident of Pittsburg, in the county of Allegheny and ally known as a hang,

. the products of the gas gas may carry, in leaving .the

State of Pennsylvania, have invented a new and useful Improvement in. Gas-Producers, of which the following is a specification. This invention relatesto gas producers. In ordinarily oper ted producers tarrv vapors and ammonia orm a component of generating chamber and instead of being an advantage they occasion an absolute loss inthe thermal eiciency of the producer. The tarry vapors, dust, ash and'such condensible vapors as the as generating chamber, are a source of di 'culty in producer apparatus as they stop or choke up 'the gas passages. A serious difficulty encountered in operating bituminous, producers lis the tendency of the fuel to bridge or arch over the fuel bed, forming what is technicjectionable' and may gerous. Y

The object of this invention, therefore, is the production of a producer in. which the at times prove vdantarry and condensible vapors arid/the monia gas formed ul-,tha'ga'sw generating chamber, are. converted into hydrocarbons of lngh thermal value.

A further object is the production of a I producer in which effective means are utilf ized forpreventing the choking up of the gas passages.

A further object is the production of a `producer,in which simple means are utilized for preventing bridging or the lphenomenon known as a hang in the fuel bed.

These and other objects I attain in a producer embodying the features herein described and illustrated.

' In the single sheet drawing accompanying this application and forming a part thereof,y

a vertical section vof a producer embodying this invention is shown.

A gas generating chamber 2 is provided with a fire brick lining 3, the inner surfaces of which are inclined from the vertical forming a truncatedl cone-shaped chamber.

.The fire brick lining is inclosed by a cylinidrical shell 4 to' which the top portion 5 1s ,"'cfonnected by a fiange angle 6,; Between the -I-Shell portion 4 and the tire brick lining." a [suitable non-conducting material 7 '1s utlll which is very ob- 1 ing 23 of the chamb -vided with a suitable fuel charging device 8 through which extends a shaft 9 operated by gears 10 and l1. Mounted on the shaft 9 and rotated by it is a fuel distributer 12 which is adapted to spr ad the fuel enterin the chamber 2.

The portingframesl and is provided with avvater' bottom 14. Mounted on cross beams which are supported by the frames 13 is a revolving grate l5 which is operated through the shaft 16, by the externally mounted gears 17 and 18. A port 19 extending through the tire generating tom 1'4. lThe chamber 21 communicates with throughan-annidaropefil thewater bottom 14 ing 23 arrangedY in the bottom of the casing 22'. The chamber 21 is provided with a tire brick lining 24 and a gas otftake port 25 which connects with the exterior gas pas-. sages of the producer. Suitably arranged sight holes 26, consisting of tubes 27, which extend through the brick lining 3, are utilized for ascertaining the condition of the ash bed. The portions of the tubes 27 extending through the chamber 21 are provided with tile covers 28 to protect it from the heat of the gases.

In starting the producer a large port 29, located in the top portion 5, is opened .and a wood tire isstarted on the ash bed, which is maintained ata suitable depth on the revolving grate 15. The air for maintaining the combustion is supplied through the bot tom portion of the producer which is not l water sealed until a good'fuel bed has been '-established. After a full live fuel bed has been attained. the water seal 14 is filled, sealing the bottom of t-he producer and ,the opener 21, and the ports 1n the cap portion 5 are closedand a blast is' admitted at the top of the chamber 2 through the opening 19. By the admission of the jblast the producer starts to generate gas which is taken otfthrough the annularly generating l chamber 21, and the fire A producer is mounted' on .suitable supbrick lining 3 near the top of the generating 70' Y arranged -ports 20. The arrangement of the gas passages choke up the gas because of thedestructivedistillation.whichy out interfering producer, and the ammonia and tarry vapors are converted into gases of high thermal value and countered in' bituminousproducers of the l bed to bridge is overcome.

The inclined walls of the gas generating chamber, the annular oitake port, and their inclosing be utilized with either an up'or still all within invention. g'

Having now described my invention what I claim 'as new and useful andy desire to secure by LettersIatent is':

In a gas producer, a truncated cone shaped ash chamber, a truncated cone shaped gas i generating chamberl above the ash chamber, the two chambers being connected together at their greatest diameters, a blast `admission port provided near ,the top of the gas generating chamber, a liquid sealedbottom for said ash chamber, an annular row o-gas delivery ports located at the juncture of the'two truncated cone shaped chambers, an annular collecting chamber surrounding the lower portion of said producer and surrounding the gas delivery ports and a water sealed recrement discharge port.

'In testimony whereof, I have-hereunto subscribed my name this twentieth day of ports 20 1s such that their combined cross sectional area, with reerence to the outlet port 25, is relatively large and, therefore, the velocity of the gas leaving the ports 20- a and passing through the chamber 21, is very slight and the ash or dust which the gas may carry is afforded an Aopportunity of' dropping into the lower part of the chamber 21 and entering the water seal 14:, through the-annular opening 23. -By this arrangement the refuse material, which is obectionable because of its tendencies to passages,.s discharged into the water seal of the producer from which it may be drawn without aecting the operation of generating the gas. The ash discharged by the revolving grate 15 also drops into the water bottom 14: rom which it may be .removed without affecting the operation of the producer.

generating chamber 2 are so inclined that the tendencies of the Jrfuelfbed to bridge or. to form a hang is substantially overcome, but the inclination is not sufficient to form between. the lining and the Jr'uel bed. The tarry-vapor and ammonia which are liberated near the top oat the gas generating chamber, pass'through the fuel bed, and
